Genetic information taken from nearly 1.1 million children is now stored on the national DNA database, official figures show, and campaigners believe that as many as half of them have no criminal convictions… The figures show that 1.09 million DNA profiles of people aged under 18 were held on the database with 337,000 under 16.

Terri Dowty, of Action on Rights for Children, sager till The Guardian: “Many children get arrested, have their DNA taken and there is no further action against them or they get a reprimand or final warning. We are collecting massive amounts of data on children, including how likely they are to be criminals, and it runs the risk that we will prejudge them.”
